    hammer2 - disable FIOSEEKHOLE
    
    * This function is returning incorrect results and needs more work.
      Disable for now.   Certain portions of the hammer2 btree may not yet
      be synchronized even when the file buffers are synced.  A SEEK_HOLE
      operation just after a file is written but prior to the next full
      filesystem may return incorrect data.  And there are other issues with
      the H2 implementation too.
    
      So... just disable it for now.
    
    * Fixes make configure; make sequences in dports where grep uses
      SEEK_HOLE to try to locate any large holes in a file.
